Mark knew exactly what the host was doing by pointing him out like this. This was a memorial service, but it was also a charity event that would lead to people bringing out money. By pointing out Mark, they were basically ensuring that people would want to donate more, either to bring attention to themselves as well or to impress Mark by making him aware of their generosity. And since Mark had been praised like this now, the hosts knew that it would be harder for Mark to not give even more than he had intended to. They were basically trying to get Mark in a good mood. It wasn't a bad tactic as far as Mark was concerned.
Mark understood all this because it was a typical business tactic that people used when trying to secure deals, so he was used to it and didn't feel irritated by it at all.
